Running lean...yeah we had problems controlling the fuel map to get a steady 12:1. I was feeding the fuel rail only from one side of the rail. I have changed that to dual fed recently. also, I am running stock pump at 9/12v configuration with a secondary pump running at 12 on ignition. I was wondering what causes the fuel to be sp sporadic. The correction on the S-AFC was +7 on one NE-point then - on the next 500 rpm. Does anyone know what cause this problem?
Wow man. 650 is a lot of juice. I'm just hoping to come somewhere close to 500 before I start adding on the fuel system, rpm upgrade with springs, and cams, and associated support equipment. I think my fuel system is completely maxed out right now, so hopefully the RPS stage 3 sprung hub clutch with lightened flywheel will free up some horsepower. Just 35 more hp!!!!!!! That's the goal. Someday, I'll be at the 650 mark, but I really need to get used to it all now. Post those numbers when you get the fuel checked out. I interested in what the T-78 can do.
